inner diameter will be fixed for a given spool, outer diameter could be measured.

There’s also formulae for calculating the length of a *Flat* Archimedean spiral Coil given thickness per layer and inner and outer diameters.

Basically the interface will tell you that you don’t have enough filament left, but as long as there’s a cartridge in place you can tell it to print anyway. The solution went with still uses the cartridges to ‘trick’ the machine into printing.

We’re sure this provides some nice functionality for those looking to press a button and walk away. They contain a spool of filament, but also include a chip which reports back the filament color and length remaining. We’re skeptical about the Cube 3D printer’s cartridges. This led him to print a feeder for his Cube 3D printer. Crunched the numbers and found out he could get filament for his 3D printer in bulk for about one-fifth the cost of the cartridges the company sells.
